HAY-CARRIER.

SPECIFICATION forming part of Letters Patent No. 340,913, dated April 27, 1886A Application filed January 30, 1885.

To all whom it may concern,.-

Be it known that I, `EDWIN L. HALL, of Deavertown, in the county of Morgan and State of Ohio, have invented a new and useful Improvement in Hay-Carriers; and I do hereby declare that the following is a full7 clear, and exact description of the same.

My invention relates to hay-carriers, and is an improvement upon that class of hay-carriers in which a frame moving upon trucks is provided with jaws adapted to operate in connection with astem or projection on the hoisting-pulley, which engages with the jaws, and also releases the stop and catching mechanism.

My invention is shown as embodied in a two-way carrier, but parts of it are applicable "to one-way carriers, and I do not limit myself in this respect.

The invention consists,iirst,of an improved gravity-catch; secondly,ofan improved frame; thirdly, of a locking-bolt adapted to fall and hold the carrier in place; fourthly, of inclined edges of the upper opening of the neck of the carrier for lifting the gravity-catch; also, of devices for opening the catch.

It consists, further, in dividing the gravitybolt and providing cut-away portions in the inclined edges, whereby the bolt is made to act as a stop and catch, and of various details,all hereinafter set forth and claimed.

In the drawings, Figure l shows a side elevation of the carrier in place upon the track, and also the catch-bolt. Fig. 2 is a central longitudinal section through the carrier and catch-bolt, the carrier being shown in a locked position. Fig. 3 is a vertical section on line x m of Fig. 2, showing the bell-shapedclutch as spread by the track-iron. Fig. t is a perspective view of the neck, showing how it is formed on its upper edge `to suit the divided form of bolt. Figs. 5 and 6 are detail views of the catch-bolt. Fig. 7 shows a bottom view of the track-iron. Fig. 8 is a detail view of the clutch-jaws, showing them in position to hold the load.

In these drawings,A is thetrack upon which the carrier moves, and B represents the main frame of the carrier, provided with trucks b, (one pair at each end,) fitted to bear upon the track.

The main arms a a are preferably connected by bars b', and this part of the frame is preferably cast in one piece. The lower part of Serial No.154,439. iNo model.)

this frame of the carrier is provided with a cylindrical neck having a vertical opening or chamber.

The bracket D is shown as composed of two pieces, p p', which maybe put on the neck and held by bolts ef at the ends, and is supported on the neck by a rim, g, the bracket being held loosely upon the neck and adapted to turn to any position required as the carrier runs one way or the other. One end of the bracketcarries the main hoisting-wheel E, turning upon the bolt e'. In the other end is left a hole, G, for the end of the hoistingrope. The bracket may be made, however,oil one piece, in which case the enlarged rim g would be omitted, and the bracket would be supported on the neck in any convenient way. lVithin this neck are pivoted the catchingjaws j f. rIhey form, substantially, a bellshaped mouth to receive the stem or eXtension of the hoisting-pulley. The division of this bell-shaped mouth is longitudinal of the carrier, andthe two parts are pivoted to swing laterally on the inside of the neck.

The inner or upper end of the bell-mouth is adapted on each side to receive and catch the head on the upper end of the stem of the hoisting-pulley. The two parts of the bell-shaped mouth are adapted to open below by gravity, so as to close the upper or catching end and normally assume this position. The stem in entering throws the upper ends of the bell parts slightly outward, and they return by gravity and catch the stem. Each side of the gravity-catch has an upwardly-extended arm which projects above the opening in which the catch parts are pivoted, and these arms are adapted to be spread by means hereinafter described. As the carrier approaches the catch-bolt and stop mechanism, and as the arms are spread, the supports of the bearings of the stem of the hoisting-pulley are separated and the hoisted pulley is allowed to drop. By this arrangement I avoid the use of springs, and at the same time simplify the construction and make it more compact and less liable to get out of order.

My improved catch and stop mechanism is shown in Fig. 1 in section, the face of it being shown in Fig. 7. It consists of a plate, L, having a hollow shank, Z, with an opening in the plate through tothe face thereof, as shown at m. In this shank is placed a bolt, M, hav- ICO IOS

ing an enlarged head to limitits upward movement, and adapted to project through the plate into the path of the carrier in line with the stem. ihe plate is set upon the under face of the track, and the bolt iits loosely, so as to freely rise and fall. The edges of the upper part of the neck of the carrier-frame are inclined, as shown at n n, so that as the carrier approaches the catch-bolt the lower projecting end of it rides up the incline, andis thus lifted until it passes over the incline, when it drops and locks the carrier in position. The edges im are near enough to each other to locate the bolt when it drops directly over the catch of the bellmouth, so that when the stem of the hoisting-pulley rises it may lift the catch-bolt and release the carrier and allow it to move on the track. The whole action is thus automatic, the catclrbolt being lifted by the incline edge, dropping when the carrier has caused it to pass the edge to lock the carrier in place, while the stem of the hoisting-block lifts the bolt and releases the carrier at the instant when the stem is in position to be. caught by the gravityeatch.

The plate L is of the shape shown in Fig. 7. It is doubly wedged, extending equally in both directions from the catch-bolt. and directly in the pat-l1 of the two arms k k. The plate extends downward below the under surface of the track, so that as the carri er approaches the arms are spread by the wedge shape of the plate, whichever way the carrier be moved. /Vhen the central part of the carrier reaches the central part of the plate, the arms are fully spread, and the stern of the hoistingpulley is released.

I have thus far described the gravity-bolt as a catch, but I have also shown it constructed to operate as a stop. For this purpose it is divided into two parts, b b2, the division being longitudinal of the track. The parts are adapted to move independently, and are suitably limited in movement, so that they may drop only the necessary distance.-

The upper incline edge of the neck openings, heretofore referred to, which serves to lift the bolt, is cut away from side to center, as shown at 2 2, the cut-away portion 2 on one side being oppositethe high portion 3 on the other side. The cut-away portions are adapted to serving to prevent the carrier from moving beyond the proper position and the other part preventing it from rebounding. rlhe construction being symmetrical, it acts precisely7^ the same in either direction.

I do not limit myself as to this divided conwhich holds the carrier, Vand the gravity-catch are equally applicable to a one-way carrier in which the bolt need not be divided, though the opening into which it falls should be slightly elongated.

The frame and bracket may be adapted to a Oneway carrier simply by fixingthc bracket on the neck by a set-screw.

Having thus described my invention, what I claim as new isl. In a haycarrier, a two-part bell shaped gravity-catch having its upper end adapted to receive and catch the stem of the hoistingpulley, and having also upwardly-extending arms adapted to be spread by the plate on the under side of the track, substantially as described.

2. In a hay-carrier, a two-part bell-shaped gravity-catch pivoted in the lower hollow extension or neck of the carrier-frame,'and having upwardly-extending arms adapted to be opened by a plate on the under side ofthe track, combined with a gravitybolt,and with the inclined edges at the upper opening of the carrier-neck, substantially as described.

3. ln a hay-carrier, the combination, with the inclined edges at the upper opening of the carrier-neck, of a gravity-catch bolt adapted to be lifted by the incline and to drop into the opening, substantially as described.

4,. In combination, in a hay carrier, a gravity-catch for the stem of the hoistingpulley, located within an opening in the carrier neck, and having upwardly-extending arms, the said opening having inclined upper edge, a gravity locking-bolt adapted to be lifted bythe inclined edge of the opening, and a plate on the under side of the track adapted to spread the arms of the gravity-catch` and release the stem of the hoistingpulley, substantially as described.

5. A locking-bolt set in thetrack and adapted to fall and project below the under surface thereof, in combination with a carrier having a central chamber and suitable catch for the stem of the hoisting-pulley, said chamber being adapted to receive the loeking-bolt, substantially as described.

6. In a hay-carrier, the combination, with a locking mechanism for the stem ofthe hoisting-pulley and the inclined edges at the upper opening of the carrier-neck, of the cut-down portions 2 2 and a divided lockingbolt, substantially as described.

In testimony whereofI have signed my naine to this specification in the presence of two subscribing witnesses.
